Four nuns killed in retirement home shooting
Gunmen have stormed a retirement home in the Yemeni city of Aden, killing 16 people including four nuns, security officials said.
The gunmen separated the Indian nuns from the others and shot them, then handcuffed the elderly people and opened fire again, the officials said.
The home is in the Sheikh Osman district of Aden.
The southern city descended into lawlessness after a Saudi-led coalition recaptured it from Shiite Houthi rebels last summer.
Islamic State has claimed a wave of attacks in Aden, including a suicide bombing that killed the governor and several assassination attempts on senior officials.
